anti-materiel rifle An anti-materiel rifle (AMR) is a rifle designed for use against military equipment, structures, and other hardware (materiel). Anti-materiel rifles are chambered in significantly larger calibers than conventional rifles and are employed to elimin ...
designed and marketed by Anzio Iron Works. It is the first American anti-materiel rifle designed and mass-produced for public sale with a bore diameter in excess of .50 caliber in over 80 years. The rifles are available in three calibers, with the rifle's predominant chambering being the 20mm Vulcan caliber.

Performance

At approximately of kinetic energy, the 20mm round, as fired out of the Anzio rifle, has nearly four times the energy of the .50 BMG cartridge fired out of a comparable rifle, which is around of kinetic energy. The

, the second most powerful African big game rifle cartridge, has around of kinetic energy. This makes a 20mm Anzio rifle 5.85 times as powerful as a rifle chambered in .600 Nitro Express. The Anzio 20/50 has approximately of kinetic energy with an bullet. It does this by taking the .50 BMG projectile, which already is relatively large and travels extremely fast, and increases the already supersonic bullet to over 1.3 times its normal flight velocity, creating more kinetic energy without the need for a larger and heavier projectile. Though its kinetic energy is significantly lower than the 20mm round, it is almost as effective due to its smaller surface area, meaning that it has less material to punch through, making it easier to penetrate, but the lighter bullet makes transferring energy over longer distances and into targets less efficient.
